EXERCISING APPARATUS, (MARKING DEVICE.)

Specification of Letters Patent.

Application filed April 15,1912.

Serial No. 691,010.

To all whom it may concern Be it known that I, Mnxron B. REACH, citizenof the United States, residing at Chicopee, Massachusetts, have inventedcertain new and useful Improvements in Exercising Apparatus, (MarkingDevices,) of which the following is a specification.

My invention relates to exercising apparatus, and particularly to theform known as the vaulting bar or Swedish bar in which a boom orhorizontal bar is carried by uprights adjustably, though it will beunderstood that my invention is not limited in this respect, but may beapplied in other situations where one member is to be adjusted inrelation to or upon another member and where markings or graduations arecarried by or associated with the fixed member to show the differentheights or the positions the adjustable member is to occupy.

In the accompanying drawing Figure 1 is a sectional view of an apparatusembodying my invention; Fig. 2 is a front View of the upright orperforated post with the markings showing through the openings. Fig. 3is a plan view of a section across the upright showing the markingdevice in its relation to the upright and showing also the coupling forconnecting the cross-bar with the upright.

In the form of apparatus selected to illustrate my invention, 1indicates upright posts or standards for supporting a cross bar or boom2, the connection between the cross bar and the uprights being made bycouplings 3 at the ends of the boom or cross bar, the said couplingscarrying suitable devices for fastening the same at different heightsalong the upright, and including pins 4, one for each coupling, to enteropenings in the uprights, said pins being preferably spring pressed andalso associated preferably with certain clamping means 5, such, forinstance, as that shown in application of Anthony Couture, executedApril 3, 1912. In order to mark the uprights with gracluations,difficulty has heretofore been experienced, because if the figures ormarkings indicating the different heights are painted on the uprightsthey quickly run off, and if these markings are stamped in the uprightsthis is a costly operation, and a method which frequently distorts thetubing of which the uprights are made. In carrying out my invention, Iemploy a member carrying the markings, and applied to the interior ofthe tubing, this member being arranged opposite the perforations in thetubing, so that the markings will show through these openings. In itsbest form this member consists of a tape or like member (3 which issuspended within the upright at about one-half inch away from theopenings which are about nine-sixteenths inch in diameter. The lower endof the tape is fastened by a spring 7 under tension. This tape is formedof material which will provide a light background, the markings orfigures appearing thereon in black, and coming opposite the holes in theupright. It will be observed from this that the markings are carriedentirely independent of the exterior surface of the uprights, leavingthese surfaces free from stampings or marks painted on.

In manipulating the device to change the adjustment of the cross bar onthe vertical standard 1, the handle 8 is turned, causing the screw 9 tomove outwardly or toward the left in Fig. 3, and when a certain positionof this screw is reached, pressure on the handle in a direction axiallyof the screw will, through the yoke 5, cause the pin 4 to move to theright out of the opening in the standard 1 and against the-pressure ofthe spring 10, and then by moving the cross bar and the bracket up ordown on the standard 1 and bringing the pin 4 into alinement with thedesired perforation and. releasing the pressure on the handle 8, thepin, under the tension of the spring 10, will enter this perforation,and then by turning the handle 8 and causing the screw 9 to act on theyoke 10, the said yoke will be drawn to the left and will be clampedagainst the exterior of the standard 1, thus securely holding the partstogether.

I claim as my invention:

1. In an exercising apparatus, a tubular member having perforations, asecond mem ber adjustable on the tubular member and having means forfixing the same thereto, and markings on the interior of the tubularmember showing through the openings, substantially as described.

2. In combination in exercising apparatus, a tubular supporting member,a second member adjustable thereon, said tubular member havingperforations, and a member within the tubular member carrying thePatented Au 20, 1912. V
